Gadgets : USB GPS dongle GT-730FL-S

In 2013, I bought a GPS dongle with a USB interface, brand CanMore for doing tests at work. The dongle proved to be a good buy. For the money, this is super value. Only when walking in cities with sky scrapers, you get errors due to reflections of the GPS signals. The errors are not catastrophic. It's just that the indicated track is not the track you took on the ground.

Back in 2013 I used a multi stage method to get to the data:

Install the CanWay software on a Windows laptop
Connect the GPS dongle to the laptop
Transfer GPS data to CanWay software
Export GPS data as GPX file
Copy GPX files to a USB stick (for Windows the network is just for playing)
Copy GPX files off USB stick to Linux machine
Process GPX data with GpsPrune or GpsMaster

This time I wanted to skip the Windows laptop as intermediate step, with the help of GpsBabel. According to the net, GpsBabel is able to communicate with the 730FL.

I got myself gpsbabel-1.5.3.tar.gz off the gpsbabel website and did as follows:

download source tarball
create ~/Bld/GPS
copy tarball to ~/Bld/GPS
extract tarball : tar zxf gpsbabel-1.5.3.tar.gz
if you look at 'ls' you see you did well to put the lot in its own directory
issue : ./configure

issue : make

You get a lot of warnings, like:

mmo.cc:1346:40: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
       if ((t.isValid()) && (t.toTime_t() < time)) {
trackfilter.cc:905:102: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
           inside = ((wpt->GetCreationTime().toTime_t() >= start) && (wpt->GetCreationTime().toTime_t() <= stop));

done:

jan@oxygen ~/Bld/GPS$ ls -lh gpsbabel
-rwxr-xr-x 1 jan users 16M Feb 12 11:00 gpsbabel*

become root and put executable in central location:

jan@oxygen ~/Bld/GPS$ su
Password: 
root@oxygen /home/jan/Bld/GPS$ cp gpsbabel /usr/local/bin/
root@oxygen /home/jan/Bld/GPS$ exit
exit

We just compiled gpsbabel and installed it on the system.

Now, those are an awful lot of warnings.... and then the compiler says it's a clean compile...

First, Make sure you have a data directory, in my case /home/jan/Data/gps, then test the /dev directory. Slackware creates /dev.ttyUSB0 and /dev/serial/*

And after a lot of testing and trials this is the best I get:

skytraq: Can't find skytraq device on '/dev/ttyUSB0'

It may be my device has too old firmware.

skytraq: cannot set new location

Skytraq Venus found. Minicom can read live data off it, using the command, as root,

minicom -b 38400 -D /dev/ttyUSB0

Bottom line

GpsBabel cannot read my GT-730FL-S dongle. Sometimes it detects the chipset, but it cannot read from the device, whereas minicom captures the live data.

Are the multiple warnings, issued in the make process, the problem? Anyway, for the time being I just need to use the Windows detour.
